Guys I don't know why this code isn't working. It's fairly straight forward and should work. I've tried everything, even changing the limits in the php.ini file. Please help...

<!DOCTYPE html>
<html lang="en">
<body>
<?php echo $_POST["username"];
var_dump( $_POST );
?>
<form action="" method="post">
    <input type="text" name="username">
    <input type="submit" value="Okay">
</form>
</body>
</html>

what does it mean "it doesnt work"? It prints nothing? – insider Aug 31 '17 at 23:56
It says "Notice: Undefined index: username in D:\wamp\www\Learn1\test.php on line 4" for the code on line 4 and "array empty" for the code on line 5 – Abraham Kyewalabye Sep 01 '17 at 00:00
I tested your code, it works fine, so it's not the code.... of course I get the errors you report when I load the page for the first time, but not when I submit the form, then I get the expected results. If your problem also only exists on first load, then add `if (isset($_POST)) { ...... }` around the two lines to PHP code. – KIKO Software Sep 01 '17 at 00:03
Well I don't like the sound of this – Abraham Kyewalabye Sep 01 '17 at 00:04
I keep clicking the submit button but I just keep getting the same errors. Perhaps it's not submitting ?... I keep getting the errors, every single time I reload – Abraham Kyewalabye Sep 01 '17 at 00:07
Try submitting to another page, check that it goes to the other page, if it does, it does submit. Then check `$_POST` on that other page. – KIKO Software Sep 01 '17 at 00:09
It's still getting the same errors, the same ones as on the first page – Abraham Kyewalabye Sep 01 '17 at 00:13
Then it is time for the developer tools, press F12 on Windows (?), and see the Network tab, check the parameters. You can practice this with other forms that do work, so you know what you have to look for. This will only tell you whether the form content has been submitted, not why it doesn't end up in `$_POST`. – KIKO Software Sep 01 '17 at 00:16
What am I looking for exactly ? – Abraham Kyewalabye Sep 01 '17 at 00:22
I'm thinking of bizarre things now. For instance, your field is called `username` and you're using an non-ssl secured url. Perhaps you've got software installed that doesn't allow this. Change the input name to something more innocent like 'testing'. – KIKO Software Sep 01 '17 at 00:23
Explaining the developer tools is way beyond what I can do in a comment. Sorry. – KIKO Software Sep 01 '17 at 00:24
It's still not working :( – Abraham Kyewalabye Sep 01 '17 at 00:27

Alright, sounds like a plan – Abraham Kyewalabye Sep 01 '17 at 00:30
To be honest, I'm out of ideas... ;-) – KIKO Software Sep 01 '17 at 00:31
Hahahaha, thanks anyways dude..much appreciated :) – Abraham Kyewalabye Sep 01 '17 at 00:33
